While Theron did not specifically state when the adoption took place, photos taken on the set of Snow White back in January show her snuggling with a male infant, thought to be Jackson.

Theron is currently unattached and adopted Jackson as a single mom, a situation that's just fine with her.

"I really want for myself a long-term relationship, and I have been in long-term relationships," Theron told Piers Morgan last June. "That's the kind of union that I want. The actual ceremony is not something that is important to me, but I see the importance for other people."

"I treat my relationships like marriages, I really do," she said. "[Marriage was] never something that was important [to me]."
